Stereoselective Synthesis of (E) or (Z) α-Alkenylphosphonates<i>via</i>α-Stannylated Phosphonates

Abstract

Abstract α-lithiostannylalkylphosphonates react with aldehydes with the complete elimination of the organotin moiety. The stereoselective formation of the (E) or (Z) α-alkenylphosphonates is closely dependent on the tin substituent.
